Ester

From WikiMD's Wellness Encyclopedia

(Redirected from Carboxylate ester)

Ester is a chemical compound derived from an acid (organic or inorganic) in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group. In other words, esters are the most common form of carboxylic acid derivatives. They are characterized by the presence of a carbonyl group adjacent to an ether group.

Chemical Structure[edit | edit source]

Esters are characterized by the presence of a carbonyl adjacent to ether. The general formula of an ester is R-COO-R', where R and R' are any organic groups. The larger R and R' groups are, the more complex the ester.

Formation[edit | edit source]

Esters are formed by condensation reaction between a carboxylic acid and an alcohol. This reaction is known as esterification. The reaction is catalyzed by acid, usually concentrated sulphuric acid. The reaction produces an ester and water.

Uses[edit | edit source]

Esters have a wide range of uses from the manufacturing of synthetic flavors and fragrances to biofuel production. They are also used in the production of polymers and plasticizers.
